A corded vacuum cleaner typically uses about 1,000-1,440 watts, roughly 1,000 W for a full-size upright. Compact models use around 500-800 W, and cordless stick vacuums only draw their charger's small load.

Watts by model and setting
Most vacuum cleaner models draw between 500 and 1,440 W while running; a typical one draws about 1,000 W. 1,000 W x 15 minutes/day. Cordless stick vacuums only use their charger (typically under 100 W).
- Motor size: full-size uprights and canisters approach the 1,440 W (12 A) limit for a 120 V plug
- Power mode or suction setting
- Powered brush heads add load
- Cordless models move use to a charger rated under about 100 W
Running a vacuum cleaner on a generator or power station
- Generator: at least 1,000 running watts and 2,500 starting watts (running plus the 1,500 W start surge, the cautious way to size it). Check both numbers on the spec sheet. A generator rated 3,000 W or more covers it with room to spare.
- Power station: continuous output of at least 1,000 W and a surge rating that covers about 1,500 W. Pure sine wave output is the safe choice for motors and electronics.
| Power station capacity | Estimated runtime |
|---|---|
| 500 Wh | 0.4 h |
| 1,000 Wh | 0.8 h |
| 2,000 Wh | 1.7 h |
| 3,000 Wh | 2.5 h |
Based on 1,000 W average draw and 85% usable capacity.
- Plan for 1,500 W or more of surge capacity on a power station or inverter generator
- Cordless vacuums are easy to recharge from a power station
- Run any generator outdoors, well away from doors, windows and vents; never in a garage or basement, because of carbon monoxide.

Questions people ask
Can a 1500 W power station run a vacuum?
Often yes for vacuums rated under about 1,200 W, but the start surge can trip smaller units; check the vacuum's label.
How many amps does a vacuum use?
Typically 8-12 A at 120 V; 12 A (1,440 W) is the usual maximum for household vacuums.
